Description

本発明は、増築に際し増築部分を再利用が可能な構造で構成された集合住宅及びその改修方法。   The present invention relates to an apartment house having a structure in which an extension part can be reused in the case of extension, and a method for repairing the apartment house.

数多く建築されてきた公営集合住宅の間取りは、昭和２６年に発表されて公営集合住宅の中心となった５１Ｃ型住宅などであり、延べ床面積が約１０坪程度の２ＤＫが主流である。現在の集合住宅の間取りが、延べ床面積２０坪前後の３ＬＤＫが主流であることを考えると決して広い間取りではない。したがって、既存集合住宅では、家族構成やライフスタイルの変化に伴い居住面積の拡大への要求も多くなってきている。 The layout of public housing complex, which has been built many times, is 51C type housing that was announced in 1951 and became the center of public housing complex, and 2DK with a total floor area of about 10 tsubo is the mainstream. Considering that the current layout of apartment buildings is 3LDK with a total floor area of around 20 tsubo, it is not a wide floor plan. Therefore, in existing apartment houses, demands for expanding the living area are increasing with changes in the family structure and lifestyle.

また、我が国における集合住宅のストックは現在相当数存在する。その中でも、公営集合住宅は鉄筋コンクリートで昭和４０年代に建築されたものがほぼ半分を占めており、エレベーターのないものが高い比率を占めている。特に、中層集合住宅（５階建てまで）はエレベーターの設置義務がなかったため、階数が多い集合住宅であるにも拘らず、エレベーターのないことが多い。高齢化社会を迎え、そういった集合住宅にもエレベーター設置やそれに更に進んだバリアフリー対応が必要になってきている。
集合住宅のエレベーター設置については、例えば、特許文献１記載の発明では、階段室型集合住宅にエレベーターを設置する際に、階段室の踊り場に近接してエレベーター後付用構造体を設け、その構造体の２階以上の各階床面と既存建物部分の各階床面とをブリッジを介して水平に連結し、既存階段室の階段は撤去する方法が記載されている。
２００３−１３６１５号公報 In addition, there are a considerable number of stocks of collective housing in Japan. Among them, public apartments are reinforced concrete that was built in the Showa 40s, accounting for almost half, and those without elevators account for a high percentage. In particular, middle-rise apartments (up to 5 floors) were not obliged to install elevators, so there are many elevators in spite of the fact that the apartments have many floors. With the aging of society, it is necessary to install elevators and further advance barrier-free measures in such housing complexes.
As for the elevator installation of an apartment house, for example, in the invention described in Patent Document 1, when installing an elevator in a staircase type apartment house, an elevator retrofit structure is provided in the vicinity of the landing of the staircase, and the structure There is described a method of horizontally connecting each floor surface of two or more floors of a body and each floor surface of an existing building through a bridge, and removing the stairs of the existing staircase.
2003-13615 gazette

以上のような、集合住宅の居住面積の拡大やエレベーター設置に対する解決策として一般的な解決方法としては、建替えや増築などの手段がとられている。しかし、建替えには工期や費用がかかるなどの問題がある。また、鉄筋コンクリートの集合住宅は、解体した材料のほとんどが廃棄処分することになり、最近の資源有効活用の高まりからも建替えのようなスクラップ・アンド・ビルドといった手法が見直しを迫られている。   As a general solution as a solution to the expansion of the residential area of the apartment house and the installation of the elevator as described above, measures such as rebuilding and extension are taken. However, rebuilding has problems such as construction period and cost. Also, most of the dismantled materials in reinforced concrete apartments will be disposed of, and due to the recent increase in effective use of resources, methods such as scrap and build, such as rebuilding, are being reviewed.

また、増築を行う場合であっても、通常のＲＣ造、鉄骨造などで増築をした場合、既存部分と増築部分との耐久年数の差異が問題となる。つまり、増築部分が耐久年数に達する前に、既存部分が耐久年数に達するため、その時点でその建物の寿命が決まり、建物全体の解体が必要となる。これは、特許文献１記載の発明の方法でエレベーターを設けた場合においても同様に既存部分と増築部分との差異が生じ、既存部分の耐用年数で建物全体の解体が必要となる。
よって、本発明では、この既存部分と増築部分との耐久年数の差による増築部分の耐用年数前での廃棄の防止と、エレベーター設置及び居住面積の拡大を図ることができる集合住宅を提供するものである。 Even when an extension is performed, if the extension is performed by a normal RC structure, a steel structure, or the like, the difference in the durability years between the existing part and the extension part becomes a problem. In other words, since the existing part reaches the endurance life before the extension part reaches the endurance life, the lifetime of the building is determined at that time, and the entire building needs to be dismantled. Similarly, even when an elevator is provided by the method of the invention described in Patent Document 1, a difference between the existing part and the extension part occurs in the same manner, and the entire building needs to be disassembled with the useful life of the existing part.
Therefore, the present invention provides an apartment house that can prevent the extension part from being discarded before its useful life due to the difference in the durable years between the existing part and the extension part, and can increase the elevator installation and the living area. It is.

請求項１記載の発明の集合住宅は、増築部分を再利用可能な構造の建物ユニットにより構成し、既存部分と増築部分とをそれぞれ独立した構造とし、増築部分には各住戸の構成単位内で使用する専有部分と複数の住戸が共同で使用する共用部分を設け、既存部分の各住戸と増築部分の専有部分同士を行き来可能な構造とし、各住戸の玄関は増築部分の共用部分に面して設け、既存部分が耐用年数に達した際に、取り外し可能なボルトで固定された前記増築部分の各建物ユニットを取り外して再利用することを特徴とする。 In the housing complex of the invention according to claim 1, the extension part is constituted by a building unit having a reusable structure, the existing part and the extension part are made independent from each other, and the extension part is included in the unit of each dwelling unit. A dedicated part to be used and a shared part shared by multiple dwelling units will be provided, and the existing part of each dwelling unit and the extended part of the extended part will be able to go back and forth, and the entrance of each dwelling unit faces the shared part of the extended part When the existing part reaches the end of its useful life, each building unit of the extension part fixed with a removable bolt is removed and reused .

増築部分に使用する建物ユニットの構造としては、例えば、既存部分が耐用年数（基本的には建物の構造耐力が減衰した物理的な耐用年数であるが、経済的、機能的な理由により既存建物を解体する場合も含まれるものとする。）に達した際に、各建物ユニットを固定しているボルト等を取り外すことにより、容易に各建物ユニット単位に分解取り外し可能で、レッカー等で吊り上げてトラックに積み、輸送して他の建物の構造材として再利用可能な構造などである。   As the structure of the building unit used for the extension part, for example, the existing part has a useful life (basically a physical useful life with a reduced structural strength of the building, but for economic and functional reasons, the existing building Can be easily disassembled and removed in units of building units by removing the bolts, etc. that secure each building unit. For example, a structure that can be loaded on a truck and transported for reuse as a structural material for other buildings.

増築部分を設ける位置としては、例えば、片廊下型集合住宅の共用廊下側に建物ユニットを積み上げて増築部分を構成したり、階段室型集合住宅の階段室側に建物ユニットを積み上げて増築部を構成するなど共用部分に近い側に設けることが集合住宅の外観や居住機能を損なうことがなく好ましい。   The location of the extension part is, for example, building the extension part by stacking the building units on the shared corridor side of the one-way apartment building, or building the extension part by stacking the building units on the staircase side of the staircase type apartment house. It is preferable not to impair the appearance and living function of the apartment house, for example, to be provided near the common part.

既存部分と増築部分とは、それぞれが独立した構造とする。つまり、連結部を直接固定するのではなく、連結部にゴムなどを挟み込み、いわゆるエキスパンションジョイントとする。これは、地震や台風の際に、既存部分と増築部分が異なる振動特性を有するためである。   The existing part and the extension part have independent structures. That is, the connecting portion is not directly fixed, but rubber or the like is sandwiched between the connecting portions to form a so-called expansion joint. This is because the existing part and the extension part have different vibration characteristics in the event of an earthquake or typhoon.

増築部分には、各住戸の構成単位内で使用する居室、廊下、浴室、洗面、便所などの専有部分と、エレベーター、エレベーターホール、玄関ホール、共用廊下、共用階段などの共用部分が設けられる。各住戸の玄関は増築部分の共用廊下に面した位置に設けられる。この際、既存部分の玄関をそのまま残し併用して使用する構成であってもよい。
また、既存部分との行き来は、渡り廊下などを使用して、既存部分の専有部分と増築部分の専有部分との間で行われる。なお、既存部分の共用階段と行き来するために増築部分の共用部分との間に渡り廊下などを設けて行き来可能にする構造を併用してもよい。 In the extension part, there are exclusive parts such as living rooms, corridors, bathrooms, bathrooms, toilets, etc. used in the unit of each dwelling unit, and common parts such as elevators, elevator halls, entrance halls, common hallways, and shared stairs. The entrance of each dwelling unit is located at the location facing the shared corridor in the extension. At this time, a configuration may be used in which the entrance of the existing part is left as it is and used together.
In addition, traffic to and from the existing part is performed between the exclusive part of the existing part and the exclusive part of the extension part using a transfer corridor or the like. In addition, in order to go to and from the shared stairs of the existing part, a structure that provides a crossing corridor or the like between the shared part of the extension part may be used together.

請求項１記載の発明によれば、増築部分を他の建物に再利用できる。したがって、耐久年数に達していない増築部分を有効に活用でき、資源の有効活用になる。また、既存部分と増築部分とは専有部分同士で行き来可能となっているので、既存部分と増築部分とを一体として使用でき、居住面積の拡大を図ることができる。   According to the first aspect of the present invention, the extension part can be reused in another building. Therefore, the extension part that has not reached the endurance years can be effectively used, and resources can be effectively used. Moreover, since the existing part and the extension part can be moved back and forth between the exclusive parts, the existing part and the extension part can be used as one body, and the living area can be increased.

また、前記建物ユニットを積み重ねる際に、前記建物ユニットの間に調整部材を挟み込むことで既存部分の各住戸の床面と増築部分の専有部分の床面とを略同一高さにする。さらに、増築部分の共用部分にエレベーターを設置する。 Further, when stacking the building units, an adjustment member is sandwiched between the building units so that the floor surface of each existing unit in the existing part and the floor surface of the exclusive part of the extension part have substantially the same height. In addition, it established the elevator to the shared part of the build-part.

増築部分の共用部分にエレベーターを設置する構成としては、各階の２住戸に１基の割合でエレベーターを設置した構成や、集合住宅１棟に対し１基のエレベーターを設置しエレベーターに連接した共用廊下を設けて各住戸に連絡する構成などが使用できる。   As for the configuration of installing an elevator in the common part of the extension, there is a configuration in which one elevator is installed in two dwelling units on each floor, or a common corridor in which one elevator is installed in one apartment building and connected to the elevator. It is possible to use a configuration in which a dwelling unit is provided to contact each dwelling unit.

既存部分の各住戸の床面と増築部分の床面とは略同一高さにするには、既存部分の階高と、増築部分の階高を合わせたり、建物ユニットを積み上げる際に建物ユニットの間に調整部材を挟みこんで高さを調整したりして略同一高さにする手段などがある。なお、多少の段差ができた場合は、緩勾配のスロープや階段を用いて緩和することが好ましい。 In order to make the floor surface of each existing unit in the existing part and the floor part of the extension part approximately the same height, the floor height of the existing part and the extension part are matched, or when the building unit is stacked, There are means for adjusting the height by sandwiching an adjustment member between them to make the height substantially the same. In addition, when a certain level | step difference is made, it is preferable to relieve | moderate using a gentle slope and a staircase.

請求項２記載の発明によれば、エレベーターの使用により、垂直方向への移動が容易に行えるようになる。また、既存部分の各住戸の床面と増築部分の床面が略同一高さとなっているので既存部分と増築部分の専有部分同士、及び共用部分から専有部分への水平移動も容易になる。   According to the second aspect of the present invention, movement in the vertical direction can be easily performed by using the elevator. Moreover, since the floor surface of each dwelling unit in the existing part and the floor surface of the extension part are substantially the same height, horizontal movement from the exclusive part of the existing part and the extension part and from the shared part to the exclusive part is facilitated.

請求項３記載の発明の集合住宅は、請求項１又は請求項２記載の発明の集合住宅であって、主な水周り設備を前記増築部分の専有部分に設けることにより、既存部分の居室面積を拡大させることを特徴とする。   The housing complex of the invention according to claim 3 is the housing complex of the invention according to claim 1 or claim 2, wherein the main room area is provided in the exclusive part of the extension part, so that the area of the existing part is It is characterized by expanding.

FIG. 2A is a cross-sectional view of the staircase type apartment house after extension. FIG. 2B is a plan view of the reference floor of the staircase type apartment house after extension.

図１は、各階に複数の住戸を有する５階建てのＲＣ造の階段室型集合住宅１であり、相隣接する２戸の住戸１２，１２に対して１つの階段室１３を有する。図１（ｂ）には、階段室１３及び該階段室１３に玄関８を有する２戸の住戸１２，１２のみが示されており、他の階段室１３等は省略する。なお、階段室１３は、各階の玄関前の床面（各階床面）３１〜３５、階と階とを連絡する階段（中間に踊り場１４を有する既存階段）１５〜１８、及び一階床面３５と住戸の外部とを連絡する階段１９等からなる。なお、この階段室型集合住宅１の階高は２７００ｍｍである。   FIG. 1 shows a 5-story RC staircase type apartment house 1 having a plurality of dwelling units on each floor, and has one staircase 13 for two dwelling units 12 and 12 adjacent to each other. In FIG. 1B, only the staircase 13 and the two dwelling units 12 and 12 having the entrance 8 in the staircase 13 are shown, and the other staircases 13 and the like are omitted. In addition, the staircase 13 has floor surfaces (each floor surface) 31 to 35 in front of the entrance of each floor, stairs (existing stairs having a landing 14 in the middle) 15 to 18 connecting the floor and the floor, and the first floor surface. 35 and the stairs 19 etc. which connect the exterior of a dwelling unit. In addition, the floor height of this staircase type apartment house 1 is 2700 mm.

先ず、建物ユニット２及び建物ユニット３を用意する。この建物ユニット２及び建物ユニット３は、直方体の四隅に立設した４本の鋼製の柱と、この４本の柱の上端部を直方体の上面の辺に沿って連結した鋼製の上梁と、この４本の柱の下端部を直方体の下面辺に沿って連結した下梁とからなる骨格を有する。また、骨格の相対する上梁に野縁を差し渡し、この野縁の下面に面材を取り付けて上面を形成し、相対する下梁に小梁を差し渡し、この小梁の上に根太を取り付け、この根太の上に面材を取り付けて下面を形成する。更に、側面に外壁を設ける場合には、上梁と下梁との間に間柱を取り付け、この間柱に外壁パネルや内壁パネルを取り付けて外壁を形成する。また、トラックに積んで運搬できるように、直方体の短辺方向の長さをトラックに積んで運ぶことのできる幅略２．５ｍとし、長辺方向を略３．１５ｍとしている。また、階段室型集合住宅１の階高２７００ｍｍに合わせた階高を有する建物ユニットである。   First, the building unit 2 and the building unit 3 are prepared. The building unit 2 and the building unit 3 include four steel columns erected at the four corners of a rectangular parallelepiped, and a steel upper beam in which the upper ends of the four columns are connected along the side of the upper surface of the rectangular parallelepiped. And a skeleton composed of a lower beam in which the lower ends of the four pillars are connected along the lower surface side of the rectangular parallelepiped. In addition, the field edge is passed to the opposite upper beam of the skeleton, the upper surface is formed by attaching a face material to the lower surface of this field edge, the beam is passed to the opposite lower beam, and the joist is attached on the beam. A face material is attached on the joist to form a lower surface. Further, when an outer wall is provided on the side surface, an outer column is attached between the upper beam and the lower beam, and an outer wall panel or an inner wall panel is attached to the intermediate column to form an outer wall. Further, the length of the rectangular parallelepiped in the short side direction is set to about 2.5 m that can be carried on the truck so that it can be carried on the truck, and the long side direction is set to about 3.15 m. In addition, the building unit has a floor height that matches the floor height of 2700 mm of the staircase type apartment house 1.

建物ユニット２及び建物ユニット３は、階段室型集合住宅１（以下既存部分Ａとする。）が耐用年数に達した際には、各建物ユニットを固定しているボルトを取り外し、各建物ユニット単位に取り外しできる構成である。取り外した各建物ユニットはレッカーで吊り上げて、トラックで輸送し他の建物の構造材として再利用することが可能な構造である。   When the building unit 2 and the building unit 3 have reached the end of their useful lives, the staircase-type apartment house 1 (hereinafter referred to as the existing part A) removes the bolts fixing the building units, It can be removed. Each detached building unit can be lifted with a tow truck, transported by truck, and reused as a structural material for other buildings.

建物ユニット２には専有部分となる浴室・洗面所・洗濯置き場・便所・廊下等を予め工場で設置する。この浴室・洗面所・洗濯置き場・便所は全て床面段差が解消された仕様とする。
建物ユニット３には共用部分となるエレベーター装置２１の各階部分２１ｃ、共用のエレベーターホール１０を設ける。このエレベーター装置２１は、上下に積み重ねられた建物ユニット３内部に形成され、昇降路２１ａと昇降路２１ａ内を図示しない昇降機構により上下動するボックス２１ｂとからなる。ボックス２１ｂは、既存部分の各階の床面の高さレベルと略同一高さに合わせて設けられた増築部分の床面に着床（停止）するものである。
なお、建物ユニット２の専有部分と建物ユニット３のエレベーターホール１０に面する位置に玄関を設ける。 The building unit 2 is pre-installed in the factory with a private bathroom, washroom, laundry room, toilet, corridor, etc. The bathroom, the washroom, the laundry room, and the toilet are all designed to eliminate the floor level difference.
In the building unit 3, each floor portion 21 c of the elevator device 21 that is a shared portion and a shared elevator hall 10 are provided. The elevator device 21 is formed inside a building unit 3 that is stacked up and down, and includes a hoistway 21a and a box 21b that moves up and down in the hoistway 21a by an elevating mechanism (not shown). The box 21b is intended to be landed (stopped) on the floor surface of the extension portion provided in conformity with the height level of the floor surface of each floor of the existing portion.
An entrance is provided at a position facing the exclusive part of the building unit 2 and the elevator hall 10 of the building unit 3.

次に図２に示すように、建物ユニット２及び建物ユニット３を増築部分Ｂの構造体として配置する。建物ユニット２の短辺方向を既存部分Ａの階段室１３のある側の居室壁面に平行になるように向けて２個据付ける。その建物ユニット２に連接して建物ユニット３を各階の２戸に１基、又は、各階の１戸に１基のエレベーターの割合になるように据付ける。また、据付けた建物ユニット２及び建物ユニット３の上部に既存部分Ａと同数階の建物ユニット２及び建物ユニット３を積み上げて据付ける。なお、建物ユニット２及び建物ユニット３はレッカーで吊り上げて据付け、それぞれの建物ユニット同士はボルトにて固定する。   Next, as shown in FIG. 2, the building unit 2 and the building unit 3 are arranged as a structure of the extension portion B. Two building units 2 are installed so that the direction of the short side of the building unit 2 is parallel to the wall surface of the existing part A on the side where the staircase 13 is located. The building unit 3 is installed so as to be connected to the building unit 2 so that there is one elevator for two units on each floor, or one elevator for one unit on each floor. Further, the building unit 2 and the building unit 3 having the same number of floors as the existing part A are stacked and installed on the upper part of the installed building unit 2 and the building unit 3. The building unit 2 and the building unit 3 are lifted and installed by a tow truck, and the building units are fixed with bolts.

この際、既存部分Ａと増築部分Ｂはそれぞれ独立した構造とする。既存部分Ａの専有部分と増築部分Ｂの専有部分同士は渡り廊下４で相互に行き来可能になるようにする。連結部である渡り廊下４と、既存部分Ａ及び増築部分Ｂとの連結部にはゴムなどを挟み込みいわゆるエキスパンションジョイントとする。
なお、建物ユニット２及び建物ユニット３は、既存部分Ａの各階と同じ階高に合わせた高さになっているため、既存部分Ａと増築部分Ｂとは略同一高さになる。よって、前記渡り廊下４の前後で段差等はなく水平方向への移動が容易になる。また、エレベーター２１は各階に着床（停止）するので垂直方向にも移動が容易になる。よって、建物の外から各階の既存部分Ａに至る移動が容易になる。 At this time, the existing part A and the extension part B have independent structures. The exclusive part of the existing part A and the exclusive part of the extension part B should be able to go to and from each other in the crossing corridor 4. Rubber or the like is sandwiched between the connecting corridor 4 that is the connecting part and the existing part A and the extension part B to form a so-called expansion joint.
In addition, since the building unit 2 and the building unit 3 have the same height as each floor of the existing part A, the existing part A and the extension part B have substantially the same height. Therefore, there is no step or the like before and after the passage corridor 4, and the movement in the horizontal direction becomes easy. Further, since the elevator 21 is landed (stopped) on each floor, it can be easily moved in the vertical direction. Therefore, the movement from the outside of the building to the existing part A on each floor is facilitated.
